Radio Frequency Identification (RFID) Systems

Dr. Vuza collaborated with Philips Semiconductors Gratkorn (Austria) on the topic of anticollision methods for radio frequency communication between read-write devices and multiple data transponders. The methods have been developed with the aid of computer simulations and finally adapted and tested on a concrete device of the above-mentioned manufacturer. Dr. Vuza's work on this topic is testified by the document Partnership Certificate issued by Philips Semiconductors.

Dr. Vuza started collaborations with Gaming Partners International, Beaune (France) in 2003 and with Frosch Electronics, Graz (Austria) in 2005 on the subject of development of devices for communication with RFID transponders. The following systems have been produced so far as results of these collaborations.

· Method and Device for Synchronization of Several RFID Readers at Low Antenna Distances with Avoidance of Mutual Disturbances – Designed for Gaming Partners International; patent pending.
Two RFID readers with antennas situated in proximity and working simultaneously would disturb each other and make data retrieval not possible, even if the antennas would be separated by 125 cm. With the aid of the synchronization protocol and controller, it was possible to have three readers working in good conditions with antennas as close as 20 cm.

· RFID Reader Based on the Atmel AT91SAM7S64 Micro-Controller – Designed for Gaming Partners International in collaboration with Frosch Electronics.

· RFID Reader Based with Integrated Display – Designed for Gaming Partners International.
